PHONOC WK.

To all whom it may concern:

Be it =mown that I, THoMAs A. Emson, a citizen of the United States, and a resident of Llewellyn Park, West Orange,

county of Essex, and State of New Jersey,

. conveying meansgis suspended in an approximately horizontal planeand*is"'forwardly directed from the neck of the reproducer. This sound conveying means is mclosed within a casing which is also forwardly directed in an approximately horlzontal osition from the reproducer, which is also mclosed. The horn inclosing chamher is constructed preferably of wood.

Reference is hereb made to the accompanying drawings orming part of this specification, embodying a preferred form of my invention, and in which- Figure 1 represents a side elevation of an apparatus embodying my invention, the casing being shown in cross section; Fig. 2 represents a plan View of the same; and Fig.

3 represents a front view looking from the left inl ig. l. 4

Corresponding parts are denoted throughout. by the same reference numerals.

Referring to the drawings, the casing, represented as a whole by the numeral 1, 1s mounted upon legs or supports 2, of which there is preferably one at the forward end and two at the rearward end. The vertical partition 3 divides the casing 1 into a forward or horn inclosing chamber d and a rearward or reproducer inclosing chamber 5. The reproducer 6, mounted upon the base plate 7, is supported within chamber 5, the base plate 7 resting upon shelf 8 therein. The motor 9 suspended below base plate 7 is entirely below the shelf 8 within the chamber 5. Access may be had to the reroducer and the interior of the-chamber 5 y means of the hinged cover 10, pivotally supported by hinges ll:

The horn or sound conveying means 12 is forwardly directed from reproducer 6, the small end of the horn being attached by the usual connection to the neck of the reproducer, and the horn extending through an opening in vertical partition 3. The

horn or sound conveyor is entirely inclosedwithin the walls of chamber 4:, the horn 12 being suspended therein in any convenient manner, as by means of the supporting link 13 attached to the under side of the upper wall of the chamber. The forward end of the horn, which preferably is hell shaped, is immediately behind the front wall 14 of the horn .inclosing chamber. This front wall *is' provided with an opening through which the sounds conveyed by horn 12 may emanate, this opening being preferably provided with the grillework 15 or equivalent' device which serves the function of largely h1ding the inclosed horn, while at the same time, it does not interfere noticeably with the volume of sound passing therethrough.

The structure is or a pleasing appearance, and permits the suspension of the sound conveying means in an approximately horizontal position, whereby the loss of volume due to bends in the horn is prevented, while, at the same time, the advantages of the concealed horn are retained.

Having now described my invention, what I claim and desire to protect by Letters Patcut is as follows: i

In a phonograph, the combination with a reproducer, of a sound conveying horn forwardly directed therefrom without bend in an approximately horizontal direction, a casing comprising a chamber in which said reproducer is supported and inclosed, said chamber having a hinged cover, and a chamber inclosing said horn and extending in an approximately horizontal direction from said reproducer chamber, a vertical partition fixed in the casing for separating said chambers and having 1 an opening therein for the horn, a horizontal shelf in said reproducer chamber dividi 1' the same into upper and lower parts an on which shelf m y mww This speeification signed and witnessed this 'Zish day of August 1909..
